Hi,
Just now, I have send a email, and didn't described clearly about the
board. First the board has four cpus, and each cpu has four cores. The four
cpus are concatenated by fpga. The fisrt cpu output as the second cpu
input, the second cpu output as the third cpu input, the third cpu output
as the forth cpu input, finally the forth cpu output as host input. They
are relay on one jtag chain. I just know these about the board. And I
don't know how to write the config file. Could you help me?
And I have another board, which has single cpu same as above one. And I
have tested pass. Following the single cpu config file.
if { [info exists CHIPNAME] } {
set _CHIPNAME $CHIPNAME
} else {
set _CHIPNAME ls3a
}
if { [info exists ENDIAN] } {
set _ENDIAN $ENDIAN
} else {
# this defaults to a bigendian
set _ENDIAN little
}
